better oil

I've been using pennzoil platinum. Everyone has their favorite I guess I finally picked this as mine.
I've tried the mobil one and castrol syntec, they all seem to work about the same.

Click on the AMSOIL tab on right (sponsor). There is testing on there of all the synthetic oils. Once you are well informed, then make your choice. I converted all my vehicles to AMSOIL (since I'm now an AMSOIL dealer) and can actually tell a difference. Vehicles start easier, get better gas mileage, and have more power. Plus, they have a 25000 mile change interval. Check out the sponsors web site. (Wish I could tell you to check out my web site, but I'm not a sponsor.)
